Blockframe

Blockframe is an NFT marketplace supports anonymous bidding on the NFT market. Rather than relying on oracles to determine NFT pricing, multiple bidders will be able to place collateralized bids anonymously to establish the value of a given digital collectible. It’s made possible by zero knowledge (ZK) technology. Using zkTrees designed by Polymer Labs, the team has created “Bulk Semaphore,” a protocol designed to form market consensus for the price of an NFT through mass unidentified membership and signaling.
